SPRING RUNNING-GEAR FOR AUTOIVIOBILES.

Specification of Letters Patent.

Patented Dec. 21 1909.

Application filed January 2, 1909. Serial No. 470,455.

To all whom it may concern:

Be it known that I, CLARENCE P. Boonnx, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented a new and useful Improvement in Spring Running-Gear for Automobiles, of which the following is a specification.

This invention relates to a spring running gear for automobiles, the object being to provide a running gear which'is so constructed that the frame will be prevented from being twisted when traveling over rough roads.

Another object of my invention is to provide a running gear which is exceedingly cheap and simple in construction and one which is formed of a very few parts which are so connected that they are not likely to get out of order.

. A further object of my invention is to provide a running gear which can be readily used on any of the ordinary makes of automobiles now in use. I

Figure 1 is a front elevation of my improved running gear showing the application of the same. Fig.2 is a section taken on the line 2-2 of Fig. 1. vFig. 3 is a detail section showing the manner of connecting the truss rod to the axle.

In the drawings A indicates the frontaxle, B the rear axle which are provided with the'ordinary wheels C and D the frame upon which the body rests. The rear axle B has secured thereon adjacent each end, double bowed springs E on which is secured a bolster E upon which the rear end of the Secured on the front axle A are double bowed springs F, on which are fixed'bearing plates G in which are pivotally mounted the rounded angle ends H of an arched bar H, over which is pivotally mounted a reversed grooved arched bar I on a bolt I extending transversely through said bars, said arched bar being provided with flattened ends which are secured to the are mounted nuts for preventing the bar from spreading, and it will be seen by this arrangement that the two arched bars will be held in a'rigid position. It will be seen that by this arrangement, the ends of the bar H have a certain amount of movement in the bearings G whereby when travelingfio over very rough roads either Wheel can be lifted without any danger of twisting the frame.-

Secured centrally to the underside of the frame D adjacent each side edge, is a bracket clips N adapted to be fastened over the front and rear axles so as to hold the frame in the proper position and to relieve the driving strain.

From the foregoing description, it will be seen that I have provided a running gear which is so constructed that one front wheel and one rear wheel upon opposite sides may be raised as when traveling over roughroads without twisting the frame in any manner, thereby overcoming difiiculties now existing with gears of this character in use.

What I claim is 1. The combination with apair of axles provided with double bowed springs, of a bolster mounted on the springs of gne of the axles, an arched bar pivotally mounted on the springs of the other axle, an arched bar pivotally connected to said arched bar,

and a frame mounted on the last mentioned arched bar and the bolster.

2. The combination with a front and rear axle, of double bowed springs secured on said axles, a bolster mounted on the springs of the rear axle, bearing plates secured on the springs of the front axle, an arched bar provided with angled ends mounted in said bearing plates, an arched bar carried by said bar, a frame mounted on the last mentioned arched bar and bolster and truss'rods 190 connecting said axles to said frame.

3. The combination with a pair of axles, provided with double-bowed springs, of bearing plates secured on the springs ofone of said axles, a bolster secured on the springs of the other axle, an arched bar having" Hllflbd ends nmulliwl in Hu- Mun-in plulw m'tlilrj Szlbl brnrkrls with ilun-spw-lin ul' 1110 springs of on: of (be nxlvs. :1 rml wm- :lxlwg for i110 pur msv (lwvnbml.
